Confusion from Mixing Lunar Elevation and Phase in Visualization

Problem

Readers struggle to grasp the article's explanation of lunar elevation, motion, and phase due to ambiguous terminology and insufficient visualisation, leading some to question whether the described 'lunar terminator paradox' is real.

To me, this article conflates lunar elevation and phase. Together with the use of ambiguous terms "up", "down", "above", and "below" makes it difficult to understand the author's intent and what their software is meant to visualise.

Now, what happens if the moon is not at the horizon, but higher up at the sky? I've read your article 2 times and I still don't understand what is apparent problem, no wonder AI had trouble.

Was this known as the "Lunar Terminator Paradox" or called that anywhere before this article? So far as I can tell this seems to be entirely made up and the only references I can find are to TFA or related.
